提高工具使用寿命的发展方向之一是化学热处理,特别是碳氮共渗和氮碳共渗。P18、P9K5和P6M5钢刀具,以及40X,9XC、38X 2 MA 钢压模在带金属箱的—3017和—3018型井式马弗电炉中于70%NH_3和30%CH_4气体混合物中进行了碳氮共渗。马弗罐的容积为70米~3,在炉子工作室空间里饱和气体的交换次数为10次。为了计量井式炉中的气体供给量,研制并安装了带有控制气体消耗量和压力的装置的输气系统,同时还建立了输送天然气的自动线。
One of the development directions to improve tool life is chemical heat treatment, especially carbonitriding and nitrocarburizing. P18, P9K5, and P6M5 steel tools, and 40X, 9XC, 38X 2 MA steel molds Carbon in 70% NH 3 and 30% CH 4 gas mixtures in a metal box-type 3017 and -3018 well muffle furnace Nitriding. Muffle tank volume of 70 meters to 3, in the studio furnace space saturated gas exchange for 10 times. In order to measure the gas supply in the pit furnace, a gas delivery system with means to control gas consumption and pressure was developed and installed, as well as an automatic line to deliver natural gas.
